Be sure the antenna system is grounded so that
it can provide some protection against voltage
surges and built-up static charges.
Section 810 of the National Electrical Code
(NEC) in the U.S.A. and Section 54 of the
Canadian Electrical Code in Canada provides
information with in regard to proper grounding
of the mast and supporting structure, grounding
of the lead-in wire to an antenna discharge unit,
size of grounding conductors, location of
antenna discharge unit, connection to
grounding electrodes, and requirements for
the grounding electrode.

cabinet of the TV set
When cleaning this TV, unplug the
AC power cord. If not, it may result
in electric shock. Use a dry soft cloth
to clean the cabinet of the TV. To remove dust
form the screen, wipe it gently with a soft cloth.
Stubborn stains may be removed with a cloth
slightly dampened with a solution of mild soap
and warm water. Never use strong solvents
such as thinner or benzine for cleaning. If using
a chemically pretreated cloth, please follow the
instruction provided on the package. The
ventilation holes can accumulate dust over time.
To ensure proper ventilation, we recommend
you to remove the dust periodically (once a
month) using a vacuum cleaner.
